This is a collection of programs I wrote on the Casio fx-5800p. These programs should also work on any Casio Graphing calculator (fx-9860g, fx-9750g, Prizm) since the programming language between Casio calculators remains largely the same.

Now if I can find my fx-5800p that I misplaced last night... *sigh*. Thank goodness for notes!

Notes for the fx-5800p programs:

There are no SIGN or MOD functions. Here are the work arounds I used (see SUN):

SIGN(x):...X > 0 ⇒ 1 → X-X > 0 ⇒ -1 → X...

n MOD d:...N - D Intg( N ÷ D ) → result variable....

Table of Contents:

1. Rotation of (x, y) (ROTATEXY)2. Law of Cosines (COSINES)3. Pendulum: Period and Average Velocity (PENDULUM)4. Arc Length of a Parabola (QUADLENGTH)5. Position of the Sun (SUN)

1. fx-5800p: ROTATEXY

Rotates the coordinate (X, Y). The direction of rotation follows the conventional direction (counterclockwise). The variable A represents the angle (θ).

Hi Eddie, so I had a question for you, I'm a cnc machinist and I use some basic geometry and trig. I had a calculator by "calculated industries" it was handy. Quite clever really. All you did was enter a numerical value and press "oop, adj, hyp, angles" and it would solve for trig functions as well as Pythagorean Therom. Do you think it would be possible to write a program to do this on this calulator?
